python
import ctypes
def wake_up_screen():
# Define constants for Windows API functions
SPI_SETSCREENSAVEACTIVE = 0x0011
SPI_SETTHREADDPIHOSTINGBEHAVIOR = 0x009D
# Disable screensaver
ctypes.windll.user32.SystemParametersInfoW(SPI_SETSCREENSAVEACTIVE, 0, None, 0)
# Enable DPI awareness to prevent issues with screen waking up
ctypes.windll.user32.SetThreadDpiHostingBehavior(SPI_SETTHREADDPIHOSTINGBEHAVIOR, 1)
# Usage
wake_up_screen()
Please note that the above code disables the screensaver and enables DPI awareness, which can help prevent issues with the screen not waking up after sleep. However, it does not directly manipulate the screen’s sleep behavior. The effectiveness of this code can vary depending on the underlying cause of the issue and the specific system configuration.
